ITEM NAME:DC-DC buck power supply module 6.5v12V ~ 40V to 5V + car voltage meter USB C3E4 DC-DC buck power supply module 6.5v12V ~ 40V to 5V + car voltage meter USB C3E4 Module performance and highlights: Wide voltage range: DC4.5 ~ 40V 5V / 2A output current capacity (input voltage in the 6.5 ~ 40V to stabilize the output 5.0V voltage) One key ("output enable" button) switch USB output, a key ("low power" button) into the ultra-low power Car voltage meter can be self-calibration, there will never be a voltmeter is not accurate! The With reverse protection, reverse does not burn With over-current, over-temperature protection With USB power indicator With terminals, easy access to the line High efficiency, low ripple Module instructions: When you need to give the phone, Ipad, MP3 and other digital products when charging, touch the "output enable" button, then USB power indicator light, USB output 5.0V voltage; When you need to close the digital tube, touch the "low power" button, then the module into the ultra-low power standby mode, USB output is also shut down accordingly. Module use: Ultra-wide input voltage for automotive / battery car / motorcycle use, used to monitor the battery voltage, grasp the battery state, can be used for a variety of voltage measurement purposes. 5.0V, 2A output current capability, enough to meet a variety of USB devices, the voltage is very stable. Note: This module default D + D- short connection, compatible with most of the mobile phone charging, and set aside a variety of mobile phone identification resistor installation location, if you need to add identification resistor, please connect D + D- wire cut, add Can be. Material: metal colour: blue size: 70*30*20mm Package Including: 1 x DC-DC power supply module Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
